good for them all they have to do is record it and post the experiment. One another can confirm. That's science right? so still no observed verified two way flow. just isn't. you can't post any.
JC, have you ever heard of Ockham's Razor? It's a bit of guidance by a fellow named William of Ockham, way back when, that says - more or less - if you have two explanations for the same observation, the one that requires you make up the least number of new rules is the likeliest to be correct.
Let's set up a simple experiment. We take two identical slaps of iron. We use boiling water to heat one to precisely 100C. We leave the other out in a shaded spot so it is at ambient temperature, say 25C. Now we place them right next to each other with one centimeter separating them and monitor their temperatures over the next hour, writing all those temperatures and times down.
Now we repeat the experiment except while we heat one back up to 100C, we cool the other to 0C with a big pile of ice. When they've both stabilized, we set them next to each other again with one centimeter separation. Again we spend the next hour recording their temperatures.
I think we know what we will find. The second experiment will show the hot block cooling faster and the cold block warming faster. Tell me if you disagree.
Now, in light of the ongoing conversation on this board, we have two possible explanations:
1) Per Planck's Law, both blocks are constantly radiating photons at a frequency and intensity proportional to their absolute temperatures and their temperature trends are simply the results of the net energy flux between them: ie, the radiation going one way minus the radiation going the other way.
2) The hot block is able, by some unknown mechanism to tell the temperature of the cold block and and in a clear violation of Planck's Law, throttle its emissions so that they are NOT proportional to its own absolute temperature but to that of the colder, target block. The cold block is able, by some unknown mechanism, to also measure the temperature of the hotter block and, in clear violation of Planck's Law, completely stop its emissions, in both experiments, because the other block is warmer.
So, one answer says that both blocks are doing the same thing all the time, in accord with a number of fundamental laws of physics and exactly produces the observed temperature changes. The other answer requires that the blocks be able to tell the temperature of a separate object and throttle its radiative emissions in inverse proportion to the temperature of the target AND only in the direction of the target (the other side of the hot block would be radiating normally). Besides violating Planck's Law that say all matter constantly radiates, this solution would have to deal with targets that are far away and moving with respect to the hot block.
Which of these would William of Ockham tell you to accept?
